Constructions of perfect Gaussian integer sequences of odd prime length by Yubo LI, Miao CHEN, Tao LIU, Ying ZHANG

“…Constructions of perfect Gaussian integer sequences (PGIS) based on the cyclotomic classes were proposed.The PGIS with degree 3 and 5 were constructed respectively from the cyclotomic classes of order 2 and 4.The presented sequences with odd prime length have ideal autocorrelations.The methods solved the problem that the traditional constructions of PGIS from the cyclotomic classes have high computational complexity.As a result,this kind of sequences will be useful in the applications of wireless communications.…”

A resource allocation algorithm based on double slots by EIPeng L, IYouming L, ITing L, HOUGuili Z, UCaimei F

“…A resource allocation algorithm based on double slots was proposed to minimize the transmitting power in wireless communications.Being aware of the channel difference between the two adjacent slots,the second slot was allocated in advance partial of the data rate conventionally scheduled to the first slot when the corresponding user had perfect channel state.Consequently,most of the required data was loaded by the sub-carriers with fine channel gain and finally less transmitting power was needed.The simulation results indicate that the proposed algorithm can effectively decrease the transmitting power while meeting the users' target rate requirement.…”
